TRAP FOR WATER-BASINS, 86C.

SPECIFICATION forming part of Letters Patent No. 462,304, dated November 3, 1891. Application filed February 18, 1891- Serial No. 381,806. (No model.)

To all whom, it may concern.-

Beit known that I, WILLIAM E. DELEHANTY, a citizen of the United States, residing at Albany, in the county of Albany and State of New York, have invented certain new and usef Lil Improvements in Traps for ater-Basins, &c.; and I do declare the following to bea full, clean-and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention is an improvement on my patented one, No. 427,752, dated- May 13, 1.890, and relates to traps for wash-basins, the.

In the drawings, Figure 1 shows a vertical sectional view of my trap with the ball-valve upon its seat, and l ig. 2 a similar view with the ball-valve raised by flushing the trap.

A full description is as follows: The trap 1 has a ball-valve 4, preferably, and over the valve is a limiting device 5, which consists of a pin, preferably bent or curved at or near its ccnter'and preferably has a threaded elongated head with a slotfor a screw-driver. The ball-valve & rests on its seat, which is preferably located at the upper end of induction-opening 3, and the eduction-opening 2 is of sufficient diameter to allow of the ball at The operation is as follows: The limiting device 5 being, preferably a round pin bent or curved practically as shown, it is set so as to assume the form of an inverted arch with its apex presented to the upper surface of the valve 4. \Vhen the trap is flushed, the ball rises oil? the seat and strikes against the bent pin 5 and is deflected to one side, and, as the pin 5 presents only upwardly-inclined surfaces to substances passing through the trap, nothing can adhere to the pin 5, and valve is prevented from entering and choking eduction-opening 2.

W'hat I claim, therefore, is

In a trap having a valve-chamber and rising and falling valve therein, abent or curved limiting device passing wholly or partly across the valve-chamber and in configuration forn1- ing substantially an inverted arch, that the rise of the valve in the trap may be limited and the limiting device present an upwardlyinclined surface to substances passing into the eduction-pipes, for the purposes described.

In testimony whereof I affix my signature in presence of two witnesses.
